BRICK OR TILE CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 403,646, dated May 21, 1889. Application filed September 27, 1888. $eria1 No. 286,486. (No model.)

To all whom it may concern:

Be it known that I, ELLIS M. BURR, of Ohampaign, in the county of Ohampaign and State of Illinois, have invented certain new and useful Improvements in Brick or Tile Cutting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in cut-off mechanism for brick or tile tables; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claims.

- In the accompanying drawings, Figure 1 is a plan. Fig. 2 is a side elevation. In each of these figures portions are broken away to reduce the size of the drawings. Fig. 3 is a side elevation, in detail.

A represents a suitable base-frame with upright adjusting-screws a at the corners thereof, for supporting and adjusting the table B.

O and D are drums on which operates the endless apron F. The trunnions of these drums are 'journaled in suitable boxes connected with table B, as arealso the trunnions of rollers f, that support the upper section of the apron between the drums. Slidingboxes 0 d, operated by screws (1, are provided for shifting drum D lengthwise of the table to regulate the tension of the endless apron. From the tile or brick machine (not shown) one or more bars of clay, O, are projected onto the apron F, causing the apron to move with the bar of clay, and thus imparting motion to drums C and D. From drum C power is transmitted for operating the mechanism for cutting the bar or bars of clay into lengths during the end movement of such bar or bars of clay. On one of the trunnions of drum C is mounted gear 0, the latter engaging gear E of shaft E. Upon shaft E are mounted cam e, crank E and usually a hand-crank, E the latter being convenient for adjusting and oiling the mechanism and for other purposes.

G and H are respectively rock-shafts, journaled in suitable boxes connected with table B. Shaft G has mounted thereon two upright arms, 9 9, set in line with each other, and a depending arm, G, all of these arms being rigidly secured to the shaft and located substantially as shown. Shaft H has mounted thereon a pair of lateral arms, h h, and a depending arm, H, all rigidly secured to the shaft.

I is a rock-shaft, j ournaled in suitable boxes at the upper end of arms 9 g. 011 shaftI are mounted parallel arms I I, these latter ex tending forward lengthwise of the table and being located outside the line of apron F. From arm to arm I I and across the free ends thereof, is stretched wire 2', for cutting the clay into lengths. Arms 1 I midway thereof are connected by pitmen h with the free ends of arms h, and the lower end of arm H is connected by pitman H with crank E By revolving this crank it is evident that an u-p and-down movement will be imparted to the cutting-wire 2'. During the cutting of ,the clayathe latter is moving along endwise, andthe severing-wire, in order to make a square cut, must move in concert with the bar of clay. To accomplish this'f'I-provide the following:

The lower .0 d ct rock-arm G is connected by pitman G with the depending arm J of a bell-crank lever, the latter being fulcrumed at the elbow thereof. The lateral arm J of this lever is provided with wrist j and roller j the latter traveling on the face of cam e. The form of this cam is approximately shown in Fig. 2, and is such that, through the medium of the connecting mechanism shown, the wire 2', during the time that it is severing the bar of clay, is moved endwise of the table in concert with the clay, thus insuring a square cut across the bar of clay.

Drum C is of such diameter that with one 0 complete revolution thereof the apron F moves the length of a given number of bricks or tiles to be cut-for instance, two, three, or four tiles, as the case may be-and the relative diameters of gears O E are arranged 5 correspondingly-two to one, three to one, or four to one, as the case may be=so that shaft E makes one revolution while apron F is moving a distance equal to the length of one brick or tile. The sweep of wire 2' up and down is something more than the'vertical distance through the bar of clay to be cut, and as the Wire only comes down to the apron there is consequently ample time for the re- 5 turn-stroke of the cutting mechanism while the wire is above the barof, clay. A While toe e of cam e is in its elevated position an ii} gaging roller j wire 2' is at the extreme of its forward throw, and the arrangementof 1o crank E is such that the wire at such time is on its upstroke and above the bar of clay. When, therefore, with a slight farther ad vance oflthe cam toe ef. leaves roller-j the latter quickly descends; iiist'ance, by gfiv ity to the heel of the cam; thiis quicklyreturning the cutting mechanism rearward to e ace Qfibeginnina,
